The space shuttle Endeavour, the youngest orbiter in NASA's fleet, soared into the morning sky Monday to begin the final mission of its 19-year career.Endeavour blazed a path through the sky here at the Kennedy Space Center at 8:56 a.m.lifting off fr

Draper Laboratory and MIT have developed a satellite the size of a loaf of bread that will undertake one of the biggest tasks in astronomy: finding Earthlike planets beyond our solar system—or exoplanets—that could support life. It is scheduled to la

The Earth is surrounded by human-made orbital debris in all shapes and sizes that includes everything from abandoned satellites and leftover rocket stages to the tiniest paint chips and droplets from spacecraft.

The U.S. office that regulates the commercial space transportation industry does not need the funding increase being sought by the White House next year given the uncertainty surrounding the markets it oversees.

An incredible new theory based on the mysterious geophysics of Saturn's largest moon, Titan, proposes that a gigantic ocean of water lies beneath the planetoid. The paper is scheduled to appear in an upcoming issue of the journal Astronomy and Astro

In the name of better managing the celestial environment, the Obama administration seems to be on the verge of imposing new international constraints on the American space establishment, without consultation with the Senate. Sources in the arms-contr

China's state-run news outlets report that preparations of the country's first space station module, called Tiangong-1, are in full swing for a launch in the second half of this year and will be followed by an unpiloted spacecraft.

China has been dabbling in space station technology for years now, but until this week the nation's aims were less than concrete, mostly consisting of plans to launch testbed technologies into orbit at some nebulous future date.

If alien life is out there, it may be able to exploit more-extreme environments than scientists think, because huge gravitational forces don't seem to pose much of a problem for microbes. Several different species of bacteria can survive and reproduc

A mysterious anomaly in space seen on two NASA probes that has caused scientists to question the laws of physics may just be a trick of the light. Anomalies were seen in the trajectories of the identical Pioneer 10 and 11 deep space probes as they h
